Claim: I claim:

1. An electro-motive enema comprising:

an electro-motive pump, which can be used in any container to pump water;

a power supply unit including a box body, a lid, a bottom plate, a pilot lamp, a switch and a circuit board; and said bottom plate being loaded with a plurality of batteries; and said power supply unit able to be re-charged with a rectifier andthe power supply of a car;

a tube assembly including a rubber tube, of which one end is mounted with a connector and connected with a water tube of said pump, while the other end thereof is mounted with another connector and connected with a rectal pipe; and said rectalpipe being mounted with a sleeve plug for completely sealing an anus to prevent from leaking water;

a washing nozzle, which can be inserted directly into anus in use;

a stool-exhausting assembly including a stool bag of which one end is closed with a clamp;

a fixed pad with a rubber washer;

a belt being fastened in buckles on both sides of said fixed pad; and

a connecting adapter being mounted in a small hole of said stool bag; and the center round hole thereof being used for inserting said rectal pipe or a washing nozzle; and said sleeve plug being used for sealing the anus during enemaoperation.

Most of the conventional enema equipment might be classified as an automatic-flowing type, a hand-press type, and a syringe type, among which the automatic-flowing type is deemed the most popular type; however, such a type has to be, inoperation, hung on a support and must have a special container; further, as a result of a pressure in the rectum, the washing water is often difficult to flow into the rectum. The hand-press type is considered a reliable type, but it takes time andman-power to operate, and therefore it is merely used as a spore device. The syringe type can not be used by a user himself (or herself); in other words, the aforesaid three types of equipment are unable to meet the requirement of a user on occasions,such as at home, traveling (in a hotel) and camping (or in a car).


In order to satisfy the general requirements and the requirement of a user who has an artificial anus, the inventor has developed "A D.I.Y. Type of Electro-motive Enema", which comprises an electro-motive pump to be sunk in water; the powersupply unit of the present invention can use the commercial A.C. power, a car power supply, a rechargeable battery or a dry battery. Since the pump can be sunk in a water, no special water container is required; since a pressure valve is furnished inthe present invention, a bottle or the like may be used as a water container. The present invention also comprises a washing nozzle, it makes the washing work much easy; Moreover, the fixed pad for the artificial anus has been improved by means ofrubber and a clamp. A user can operate it without touching the water and stool and without smelling the odour at all; therefore, the present invention is deemed a reliable and sanitary enema device to meet the requirements on all occasions, such as athome, travelling, camping or others.
